Update: Facebook, Instagram, WhatsApp, Messenger and Oculus VR are back online as of 6:10 p.m. ET.
The dust has settled after Facebook’s six-plus-hours-long outage yesterday, October 4. As the social media giant’s blue website went down, so did Instagram, WhatsApp, Messenger and Oculus VR.
The company blames what it calls a “faulty configuration change.” Essentially, the routers that chauffer people’s web requests went offline. This had a rippling effect that brought down all facets of the entire company. A source told NBC News that employees couldn’t even get into conference rooms as scanning ID cards all go through the same system.
